Systems and methods for allocation of telephony resources on-demand

ABSTRACT

Organizations may employ private computer networks to enable customers to place a telephone call to customer service agents (CSAs). To maintain high customer service, it may desirable to expand the private computer network&#39;s ability to respond to customer calls on-demand. One or more requests for additional telephony resources may be submitted to a telephony resource allocation service in communication with a configurable network service. The telephony resource allocation service may determine telephony resources available for allocation to the private computer network and facilitate communication between the configurable network service and the private computer network. In this manner, additional computer private network extensions executing instances of call distribution services may also be generated and configured. Thus, the capacity of the private computer network to respond to customer calls may be expanded, while the additional private network extensions may manage distribution of calls to the CSAs transmitted over the allocated telephony resources.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No.12/624,375, entitled SYSTEMS AND METHODS FOR ALLOCATION OF TELEPHONYRESOURCES ON-DEMAND, and filed Nov. 23, 2009, the entirety of which isincorporated herein by reference.

BACKGROUND

Organizations that conduct transactions with customers (e.g.,businesses, non-profit organizations, government agencies, etc.) oftenseek to distinguish themselves by providing excellent customer service.For example, in order to address questions and concerns of potential andcurrent customers, either pre- or post-transaction, organizations mayprovide telephone numbers that facilitate contact between theircustomers and customer service agents. To facilitate telephone contactwith customers, call centers have been developed as a centralized,scalable mechanism to handle distribution of the received calls toavailable customer service agents.

The volume of calls received by an organization's call centers may varysignificantly depending upon variety of factors. These factors mayinclude, but are not limited to, time (e.g., time of day, month oryear), promotions to increase customer demand, and the like. In order toprovide a satisfactory customer experience, it is desirable thatsufficient resources are devoted to call centers to respond to projectedcustomer call volume in a timely manner. However, to constrain costs,organizations may also wish to restrict the resources devoted to callcenters to meet only the actual volume of calls received.

Unfortunately, it can be difficult to scale the resources devoted tocall centers to respond to customer calls in a timely fashion. In oneexample, changing an amount of telephone capacity provided to anorganization by a telephone provider may require a waiting period toimplement. In another example, network resources used for balancing callloads amongst an organization's call centers and/or customer serviceagents may require investments in computing resources, as well as timeand personnel to implement or dismantle. While telephone capacity and/ornetwork call balancing resources are changed to satisfy differing levelsof call demand, an organization's call centers may be over- orunder-resourced, hurting customer service or incurring elevatedoperating costs unnecessarily.

DETAILED DESCRIPTION

Generally described, aspects of the present disclosure relate to systemsand methods for allocating telephony resources on-demand (e.g.,telephone lines, telephone numbers) to an existing computer network. Forexample, the computer network may include one or more call centersincluding customer service agents that receive incoming calls from endusers. An operator of the computer network may find it advantageous toadjust the telephony resources available to the computer network inorder to meet existing or projected call demand so as to providesuperior customer service. In a non-limiting example, the computernetwork may be operated by a network-based retailer and the end user mayinclude an individual who has made a purchase from the network-basedretailer.

In an embodiment, the computer network may include a private computernetwork. Private networks may include networks that are partially orwholly inaccessible to unauthorized end users. Examples of privatenetworks may include, but are not limited to, corporate networks, homenetworks, university networks and the like. Private networks may includeone or more networks. The private computer network may further includecomputing systems and/or other networked devices.

Further aspects of the disclosure relate to providing additionalcomputer networks that execute services in support of the allocatedtelephony resources (referred to herein as private network extensions).The private network extensions may be configured to communicate with theexisting computer networks, providing substantially seamless integrationof the private computer network and private network extensions.

The network extensions, in further embodiments, may include one or morecomputing devices and/or other networked devices which execute instancesof a call distribution service. Call distribution services may performfunctions including, but not limited to, allocating, routing andmaintaining telephone connections between an end user which places acall and a customer service agent (CSA). For example, the customerservice agent may include a customer service agent operating one or morecomputing devices (e.g., computers, telephones, etc.) in communicationwith the private computer network. Connections may be establishedbetween the end user's telephone, the CSA's telephone and client devicesoperated by the CSA. The call distribution service may further connectend users and CSAs through public networks, which may include networksoperated by telephony carriers and other data carriers.

In certain embodiments, the network extensions may be executed on one ormore computing devices and/or other networked devices that are locationspecific. For example, the based upon the topology of a network, it maybe advantageous to execute instances of a call distribution service onone or more selected computing devices that are located at a specificposition in the network with respect to the private computer networksupported by the executed call distribution service. In one non-limitingexample, the private computer network and one or more computing deviceexecuting call distribution service instances may be close to eachother, with respect to network topology. In this manner, closeness ofthe computing devices executing call distribution service instances andthe private computer network may improve the call distributionperformance. In further embodiments, the computing devices upon whichthe call distribution service instances are executed may be dynamicallychanged, based upon variations in network conditions, such as networktraffic, in order to maintain or improve call distribution performance.

In this regard, a telephony resource allocation service is describedthat allocates telephony resources in response requests for telephonyresources received from a user, such as a user utilizing a usercomputing device that is part of the private computer network.Accordingly, the request for telephony resources may include a requestfor telephony resources of the type needed for a call center (e.g.,additional telephone lines for the call center, additional telephonenumbers for the call center, and a duration over which the telephonelines and/or telephone numbers are desired).

As described in greater detail below, the telephony resource allocationservice may review the request and indicate whether the request may beaccommodated in full, in part, or not at all. For example, if thetelephony resources requested by the private computer network areavailable for allocation, the telephony resource allocation service mayindicate that the request may be satisfied in full. If only a portion ofthe telephony resources requested by the private computer network areavailable for allocation, the telephony resource allocation service mayindicate that the request may be satisfied in part. If no telephonyresources are available for allocation, the telephony resourceallocation service may indicate that the request may not be satisfied.The telephony resource allocation service may further requestconfiguration information from the user utilizing a user computingdevice that is part of the private computer network in order tofacilitate integration of the user's private computer network withprivate network extensions generated on behalf of the user in support ofits requested telephony resources.

With the user's approval to allocate the indicated telephony resources,the telephony resource allocation service may further submit informationregarding the allocated telephony resources and the configurationinformation to a configurable network service (CNS). The CNS may createone or more private network extensions based upon the telephonyresources allocated for the requesting private computer network. In anembodiment in which the requesting private computer network is a callcenter, the private network extensions may provide one or more automatedcall distribution services using the allocated telephony resources.

In an embodiment, the CNS may include hardware, software andcombinations thereof and may be operative to provide the privatecomputer network with access to the private network extensions. Forexample, the private computer network may automatically interact withthe CNS to create and configure one or more private network extensionsfor use by the private computer network. In other embodiments, the useremploying a user computing device that is part of the private computernetwork may manually interact with the CNS (e.g., through one or moreuser interfaces) to create and configure the one or more private networkextensions. The private network extensions may be provided by the CNSand include multiple computing nodes that are maintained or otherwiseunder control of the CNS.

Accordingly, once the private network extensions are configured forcommunication with the private computer network, the private networkextensions, including automated call distribution operations, may beoperated as if they were a part of the private computer network. Thus,calls intended for the call center implemented as a private computernetwork may be seamlessly distributed to, and processed by, one or moreof private network extensions.

The CNS may also establish private connections between the privatenetwork extensions and the private computer network. For example,virtual private network (VPN) connections may be established between theprivate network extensions and the private computer network. Through theuse of VPN connections, connections between the private networkextensions and the private computer network may be afforded highsecurity. In certain embodiments, VPN connections may comprise secureVPN connections. In alternative embodiments, VPN connections maycomprise unsecure VPN connections. In additional embodiments, the VPNconnections may comprise combinations of secure and unsecure VPNconnections.

The CNS may also associate the telephony resources allocated to theprivate computer network to the private network extensions. In thismanner, calls that are routed to a telephone number or telephone lineallocated to the private computer network may be directed to the privatenetwork extensions executing the automated call distribution service.Owing to the connection between the private network extensions andprivate computer network, these calls may be routed to a private networkextension that implements a call distribution instance, whichsubsequently distributes the call to the private computer network (e.g.,a call center).

In this manner, telephony resources may added or removed from theprivate computer network on-demand in response to changing call volumes.In one aspect, this flexibility may reduce the need for long termforecasting of telephony demand and adjustment of the telephonyresources and private network extensions (e.g., automated calldistribution services) to meet long-term projected demand.

Instead, telephony resources may be requested for the private computernetwork in response to short term forecasts, which are likely to be moreaccurate than long term forecasts, or even in response to instantaneousdemand. In response to such requests, the CNS may create computernetworks that execute automated call distribution services and integrateof networks with existing private computer network. Thus, telephonyresources may be allocated private computer network and additionalautomated call distribution services may be provided at the time ofrequest.

Furthermore, should demand for telephony resources fall, the addedtelephony resources and automated call distribution services may beterminated. Thus, from the user's standpoint, telephony resources may berapidly changed without negotiations with telephony providers (e.g.,telecommunications operators) or incurring the expense of acquiring andmaintaining computing resources to support the additional telephonyresources.

With reference to FIG. 1, an embodiment of an operating environment 100for allocating telephony resources and providing private networkextensions to a private computer network 130 is illustrated. Asdiscussed above, the private computer network 130 may include one ormore existing private networks, such as a corporate or other privatenetwork (e.g., home, university, etc.) that is partially or whollyinaccessible to non-privileged end users. The private computer network130 may further include one or more computing systems and/or othernetworked devices.

In the operating environment 100, a user (e.g., a user having access tothe private computer network 130) may employ a computing deviceincorporated within the private computer network 130 to communicate witha telephony resource allocation service 102. The user may further submita request for telephony resources to the telephony resource allocationservice 102. Requests regarding telephony resources may be furtherdirected to a configurable network service (CNS) 105 in communicationwith the telephony resource allocation service 102. The CNS 105 maycreate and configure one or more private network extensions to provideadditional services to the private computer network as discussed ingreater detail below.

It will be recognized that many of the components described below areoptional and that embodiments of the system 100 may or may not combinecomponents. Components need not be distinct or discrete. Components maybe reorganized in the system 100. For example, the telephony resourceallocation service 102 and CNS 105 may be represented in a singlephysical server or computing system containing all of the subsystemsdescribed below or, alternatively, may be split into multiple physicalservers.

The telephony resource allocation service 102 and CNS 105 may each beembodied in a plurality of components, each executing an instance of therespective telephony resource allocation service 102 and CNS 105. Aserver or other computing system implementing the telephony resourceallocation service 102 or CNS 105 may include a network interface,memory, processing unit and computer readable medium drive, all of whichmay communicate which each other may way of a communication bus. Thenetwork interface may provide connectivity over the network 108 and/orother networks or computer systems. The processing unit may communicateto and from memory containing program instructions that the processingunit executes in order to operate the telephony resource allocationservice 102 or CNS 105. The memory generally includes RAM, ROM and/orother persistent and auxiliary memory.

In an embodiment, the telephony resource allocation service 102 mayinclude a user interface component 104 and a telephony resourcemanagement component 106. The user may employ one or more computingdevices included in the private computer network 130 to communicate withthe telephony resource allocation service 102 via one or more userinterfaces provided by the user interface component 104. Such userinterfaces may be generated by the user interface component 104 orretrieved from a memory device in communication with the telephonyresource allocation service 102, such as data store 112 in communicationwith the telephony resource allocation service 102

For example, the user may submit one or more requests for telephonyresources, including, but not limited to, telephone lines and telephonenumbers for a selected duration of time. Such durations of time mayinclude a fixed period of time, such as between date ranges. Other fixedperiods of time may include selected hours for selected days of theweek. Other time ranges may include open-ended time ranges. In oneinstance, an open-ended time range may include a time range which beginson a selected date and/or time until otherwise instructed. In anotherinstance, an open-ended time range may include a time range which startsand/or ends according to selected criteria, such as call volume receivedby call centers of the private computer network 130.

The telephony resource allocation service 102 may further include atelephony resource management component 106. In response to receiving arequest for telephony resources, the telephony resource managementcomponent 106 may determine whether sufficient telephony resources areavailable to the telephony resource allocation service 102 to satisfythe received request. For example, the telephony resource managementcomponent 106 may obtain records of available telephony resources fromthe data store 112 and compare these records with the telephony resourcerequest. Based upon this comparison, the telephony resource managementcomponent 106 may determine if the telephony resource allocation service102 may satisfy the user's telephony resource request.

For example, assume that a user submits a request for one hundredtelephone lines and ten telephone numbers. The telephony resourcemanagement component 106 may retrieve records from the data store 112 inorder to determine the amount of telephony resources available forallocation. If the retrieved records indicate that the telephonyresource allocation service 102 has three hundred telephone lines andfifty telephone numbers available for allocation, an amount which isgreater than the requested amount of telephony resources, the managementcomponent 106 may determine that the request for telephony resources maybe satisfied in full. If the retrieved records indicate that thetelephony resource allocation service 102 has only sixty telephone linesand five telephone numbers available for allocation, an amount which isless than the requested amount of telephony resources, the managementcomponent 106 may determine that the request for telephony resources mayonly be satisfied in part. If the retrieved records indicate that thetelephony resource allocation service 102 has no available telephonelines or telephone numbers available for allocation, the telephonyresource management component 106 may determine that the request fortelephony resources may not be satisfied.

In further embodiments, the telephony resource management component 106may also determine a quantity of private network extensions 120 and/orassociated computing nodes for adequate support of the requestedallocation of telephony resources. As discussed below, the privatenetwork extensions 120 may include one or more computing nodes.

In one embodiment, this determination may be made based upon the amountof telephony resources requested. For example, the telephony resourcemanagement component 106 may determine that a selected number of privatenetwork extensions 120 having a further selected number of computingnodes may be necessary to support the requested amount of telephonyresources (referred to herein as supporting computing resources). Such adetermination may be further based upon factors such as performancecharacteristics of the computing nodes (e.g., processor speed, memoryavailable, storage available, etc.). The telephony resource managementcomponent 106 may employ lookup tables, formulas, and the like determinethe supporting computing resources.

In certain embodiments, the supporting computing resources may also beconsidered when ascertaining whether a user request for telephonyresources may be satisfied in full, in part, or not at all. Thesupporting computing resources may be compared with available quantitiesof computing resources. Records of available computing resources mayalso be maintained within the data store 112.

For example, if the both the available telephony resources and theavailable computing resources exceed the requested telephony resourcesand the supporting computing resources, then the telephony resourcemanagement component 106 may determine that the request for telephonyresources may be satisfied in full. If either of the retrieved recordsfor available telephony resources and available computing resourcesfails to exceed the requested telephony resources or the supportingcomputing resources, respectively, then the telephony resourcemanagement component 106 may determine that the request for telephonyresources may be satisfied in part. If no telephony resources orcomputing resources are available, then the telephony resourcemanagement component 106 may determine that the request for telephonyresources may not be satisfied.

An indication of the telephony resources available for allocation to theprivate computer network 130 may be provided to the private computernetwork 130 for approval to allocate the telephony resources. Thetelephony resource allocation service 102 may further requestconfiguration information from the private computer network 130 in orderto facilitate configuration of private network extensions 120 for usewith the private computer network 130. The configuration information mayinclude information which enables the CNS 105 to communicate with theprivate computer network 130 in order create private network extensions120.

Upon acceptance of the offered telephony resource allocation by theprivate computer network 130, and receipt of the configurationinformation for the private computer network 130, the telephony resourceallocation service 102 may submit the information regarding thesupporting computing resources and the configuration information to theCNS 105. The CNS 105 may in turn employ at least a portion of thisinformation for creation of the one or more private network extensions120. As further discussed below, the private network extensions 120 mayfurther execute one or more instances of an automated call distributionservice (ACD) that automatically distributes calls.

In further embodiments, the telephony resources allocated to the privatecomputer network 130 may be further provided according a selectedquality of service (QoS) level. Continuing the example above, assumethat the user accepts an offered telephony resource allocation for onehundred telephone lines. The user may further be presented with optionsfor guaranteed service for ten active calls, twenty active calls, thirtyactive calls, and the like, each having different prices. For example,as the number guaranteed active lines increases as a proportion of thetotal telephone line allocation, the QoS price may be increased. QoSlevels may be further changed dynamically, as necessary. For example,QoS levels may be changed based upon factors including, but not limitedto, timing (e.g., time of day, day of week, day of year). Beneficially,tiered pricing arrangements for differing QoS may provide users with theflexibility to obtain telephony resource allocations and serviceguarantees at prices which are appropriate for his or her network.

Descriptions of illustrative embodiments of the CNS 105 may be found incommonly-owned, co-pending U.S. patent application Ser. No. 12/332,214,entitled, “PROVIDING ACCESS TO CONFIGURABLE PRIVATE COMPUTER NETWORKS,”the entirety of which is incorporated herein by reference. The CNS 105may include a manager module 110 for use in creating and configuringprivate network extensions 120 for use in conjunction with existingprivate computer networks 130. In further embodiments, at least some ofthe created private network extensions 120 may be configured to enablesecure, private access from one or more corresponding private computernetworks 130 over the network 108 (e.g., via Virtual Private Network(VPN) connections).

In an embodiment, the manager module 110 of the CNS 105 may receive theinformation regarding the supporting computing resources. The managermodule 110 may create and configure the private network extensions 120as discussed below in the specified quantity.

The CNS manager module 110 may further execute on one or more computingsystems of the CNS 105 and may provide one or more APIs that enable auser of a computing device included in the private computer network 130to programmatically interact with the module 110 to access some or allof the functionality of the CNS 105 on behalf of the user (e.g., tocreate, configure, and or initiate use of the private network extensions120). Additionally, in some embodiments, users may instead manuallyinteract with the manager module 110 (e.g., via a user interfaceprovided by the manager module 110 or the user interface component 104to perform some or all of such actions). For example, interactionsbetween the user and the CNS manager module 110 in order to create andconfigure the private network extensions 120 for the user may beinitiated when the telephony resource allocation service 102 submits theinformation regarding the allocated telephony resources and theconfiguration information to the CNS 105.

Those skilled in the art will appreciate that the network 108 may be anywired network, wireless network or combination thereof. In addition, thenetwork 108 may be a personal area network, local area network, widearea network, cable network, satellite network, cellular telephonenetwork or combination thereof. Protocols and components forcommunicating via the Internet or any of the other aforementioned typesof communication networks are well known to those skilled in the art ofcomputer communications and thus, need not be described in more detailherein.

The private network extensions 120, may each include multiple computingnodes, at least some of which are provided by or otherwise under thecontrol of the CNS 105. Each of the provided network extensions may befurther configured in various ways by the private computer network 130for whom they are provided. Each of the private network extensions 120may be a private computer network that is accessible only by the privatecomputer network 130 for which it is created. In other embodiments,though, at least some of the private network extensions 120 provided bythe CNS 105 for the private computer network 130 may be publicallyaccessible and/or may be stand alone computer networks that are notextensions to other computer networks. Similarly, while the privatenetwork extensions 120 may communicate with computer networks 130 thatare private, in other embodiments, the private network extensions 120may communicate with computer networks 130 that are not private.

Private access between a private computer network 130 and correspondingprivate network extensions 120 may be enabled in various ways. One suchway is by establishing a VPN connection or other secure connectionbetween the private network extensions 120 and computer networks 130that allow for intercommunication over the network 108 in a secure,private matter. For example, the CNS 105 may automatically performappropriate configuration on its computing nodes and other computingsystems to enable VPN access to a particular private network extension120, such as by automatically configuring one or more VPN mechanismshosted by the CNS 105 (e.g., software and/or hardware VPN mechanisms),and/or may automatically provide appropriate configuration informationto the private computer network 130 (e.g., credentials, access points,and/or other parameters) to allow a VPN mechanism hosted on the privatecomputer network 130 to establish VPN access.

After VPN access has been appropriately enabled and/or configured, a VPNconnection may be established between the private computer network 130and the private network extensions 120, such as initiated by the userusing Internet Protocol Security (IPsec) or other appropriatecommunication technologies. For example, in some embodiments, a VPNconnection or other secure connection may be established to or betweennetworks that use Multi Protocol Label Switching (MPLS) for datatransmission, instead of an IPsec-based VPN connection.

In additional embodiments, the user of a computing device included inthe private computer network 130 may also interact with the module 100to exchange additional configuration parameters for use in facilitatingcommunication between the private network extensions 120 and the privatecomputer network 130. Examples of such configuration parameters include,but are not limited to, network addresses for the private networkextensions 120 provided to the private computer network 130, networktopology information for the private network extensions 120 provided tothe private computer network 130 and network access constraintinformation for the private network extensions 120 supporting to theprivate computer network 130. Further information regarding the exchangeof information such as network addresses, network topology, and networkaccess constraints may be found in U.S. patent application Ser. No.12/332,214, entitled, “PROVIDING ACCESS TO CONFIGURABLE PRIVATE COMPUTERNETWORKS” and previously incorporated herein by reference.

In certain embodiments, the private network extensions 120 provided bythe CNS 105 may further execute one or more instances of an automatedcall distribution service (ACD) that automatically distributes calls. Asdiscussed in greater detail below, telephony resources, such astelephone lines and telephone numbers, may be allocated to a the privatenetwork extensions 120 in response to a request. These allocatedtelephony resources may be further associated, by the CNS 105, with theACD instances executed by the private network extensions 120 providedfor the private computer network 130. As a result, calls carried by theallocated telephony resources may be distributed by ACD instances,executed on the private network extensions 120, to the private computernetwork 130. The private computer network 130, which may form a callcenter including customer service agents (CSAs), may respond to receivedcalls.

A determination may also be made as to the number of ACD instances areto be executed by the private network extensions 120. The number of ACDinstances which are executed may be based, at least in part, upon thetelephony resources (e.g., number of telephone lines and/or telephonenumbers) allocated to the private computer network 130. For example, thenumber of ACD instances which are executed may be selected such that theexecuted ACD instances may distribute a number of telephone callsgreater than or equal to the maximum number of telephone calls that maybe received for distribution by the allocated telephony resources.

For example, assume that an ACD instance may distribute a selectednumber of calls over a given time period (e.g., ten). Further assumethat the telephony resources to be allocated to the private computernetwork may receive a maximum number of calls which may needdistribution over the given time period (e.g., 100). Then, in thisexample, it may be determined that at least 10 ACD instances may beneeded to distribute the maximum number of calls which may be receivedfor distribution by the allocated telephony resources (10 callsdistributed/ACD×10 ACDs=100 calls distributed) This determined number ofACD instances may be distributed to the configurable network service 105during creation of the private network extensions 120. In certainembodiments, the determination may be made by the telephony resourcemanagement component 106.

In certain embodiments, the private computer network 130 may furthercommunicate with the private network extensions 120 so as to provideinstructions to the ACD instances as how to distribute calls received bythe private network extensions 120 to the CSAs of the private computernetwork 130.

Descriptions of illustrative embodiments of a call distribution servicemay be found in U.S. patent application Ser. No. 12/192,067, entitled,“SYSTEM AND METHOD FOR AUTOMATED CALL DISTRIBUTION,” the entirety ofwhich is hereby incorporated by reference. In brief, such a calldistribution service may be represented in hardware, software andcombinations thereof and may be operative to allocate, route, andmaintain connections between an end user which places a call and a CSAof the call center implemented by the private computer network 130.Connections may be established between the end user's telephone, theCSA's telephone and client devices operated by the CSA. The ACDinstances may further connect end users and CSAs through networks suchas network 108, which may include networks operated by telephonycarriers and other data carriers.

It may be understood that embodiments of the disclosed systems andmethods may be employed both for private computer networks 130 for whichprivate network extensions 120 are not presently provided (e.g., privatecomputer network 130 for which private network extensions 120 have notpreviously been provided or private computer networks 130 for which noprivate network extensions 120 are currently provided), as well asprivate computer networks 130 for which private network extensions 120are presently provided. For example, private computer networks 130 forwhich private network extensions 120 executing one or more instances ofACD instances may submit a request for additional telephony resources iftheir call demand increases. Accordingly, additional private networkextensions 120 may be created by the CNS 105.

Instead of creating a new private network extensions 120 executing oneor more instances of ACD services, the telephony allocation resourcesystem 102 may determine whether the currently executing ACD instancesare sufficient to support the requested additional telephony resources.That is to say, are the currently executing ACD services capable ofdistributing all calls transmitted over the originally requestedtelephony resources and the additionally requested telephony resources.

This determination may be made similarly to the original determinationof the number of ACD services to be executed. The maximum number ofcalls which may be received for distribution with the addition of thetelephony resources requested for allocation is approximately equal tothe ratio of the sum of the maximum number of calls which may bereceived for distribution by the currently allocated telephony resourcesand the maximum number of calls which may be received for distributionby the telephony resources requested for allocation. As before, a singleACD instance may distribute a fixed number of calls at a given time.Thus, the number of ACD instances needed to support the requestedadditional telephony resources may be given by the ratio of the sum ofthe maximum number of calls which may be received for distribution bythe currently allocated telephony resources and the maximum number ofcalls which may be received for distribution by the telephony resourcesrequested for allocation and the fixed number of calls a single ACD maydistribute at a given time.

If the value of this ratio exceeds the number of currently executed ACDinstances, then additional ACD instances may be needed to support theadditional telephony resources requested. If, however, the value of thisratio does not exceed the number of currently executed ACD instances,then additional ACD instances may not be needed to support theadditional telephony resources requested. Put another way, if themaximum number of calls the currently allocated telephony resources andtelephony resources to be allocated may receive for distribution remainsunchanged from the maximum number of calls the currently allocatedtelephony resources, the ACD resources currently executed may besufficient to support the additional requested telephony resources.

FIG. 2A is a block diagram of the operating environment of FIG. 1,illustrating a user of a computing device in a private computer network130 submitting a request to the telephony resource allocation service102 for telephony resources. A user may communicate with telephonyresource allocation service 102 via user interfaces displayed by usercomputing devices within the private computer network 130. Such acomputing device may include, but is not limited to, a laptop or tabletcomputer, personal computer, personal digital assistant (PDA), hybridPDA/mobile telephone, mobile telephone, electronic book reader, set-topbox, camera, digital media player, and the like.

For example, the request may include a request for telephony resources.The request may be transmitted to the telephony resource allocationservice 102, and the telephony resource allocation service 102 mayfurther detect that a determination regarding available telephonyresources is needed to respond. Optionally, the telephony resourceallocation service 102 may further detect that a determination regardingsupporting computing resources is also needed to response. In certainembodiments, the telephony resource allocation service 102 may determineavailable telephony resources and, as necessary, available computingresources and an estimate of supporting computing resources in order tosatisfy the requested telephony resource request.

The telephony resource allocation service 102 may further compare theavailable telephony resources to the requested telephony resources.Optionally, the telephony resource allocation service 102 may alsocompare the quantity of available computer networks and/or associatedcomputing nodes to the estimate of a needed quantity of computernetworks and/or associated computing nodes to satisfy the requestedtelephony resource request. Based upon the results of the comparison,the telephony resource allocation service 102 may return a response tothe private computer network 130 indicating that the telephony resourceallocation service 102 may satisfy the telephony resource request infull, in part, or not at all, along with an offer of telephony resourceswhich may be.

In the response to the request for telephony resources, the telephonyresource allocation service 102 may further include a request foradditional configuration information. The returned request may indicatethat, should the private computer network 130 wish to receive thetelephony resource allocation offered by the telephony resourceallocation service 102, configuration information enabling the CNS 105to communicate with the private computer network 130 should besubmitted.

FIG. 2B is a block diagram of the operating environment of FIG. 1,illustrating the submission of configuration information to thetelephony resource allocation service 102 from the private computernetwork 130 in order to receive a specified allocation of telephonyresources.

The telephony resource allocation service 102, in turn, may submit theresources to be allocated, the configuration information, and thepreviously determined information regarding the allocated telephonyresources (e.g., the supporting computing resources in order to satisfythe requested telephony resource request) to the CNS 105. The telephonyresource allocation service 102 may further submit the number of ACDinstances needed to support the requested telephony resources. The CNSmay then create the supporting computing resources (e.g., privatenetwork extensions 120 and/or associated computing nodes, as well as ACDinstances) needed in order to satisfy the requested telephony resourcerequest. The CNS 105 may further employ the configuration informationreceived from the telephony resource allocation service 102 tocommunicate directly with the user in order to configure the createdprivate network extensions 120 for operation with the private computernetwork 130.

As discussed above, the private network extensions 120 may furtherexecute one or more instances of an automated call distribution service.The CNS 105 may also associate the allocated telephony resources (e.g.,telephone lines and/or telephone numbers) with the private networkextensions 120 created for the private computer network 130.

Once the private network extensions 120 are created and configured, aswell as associated with the telephony resources allocated to the privatecomputer network 130, the CNS 105 may return an acknowledgement to thetelephony resource allocation service 102. In turn, the telephonyresource allocation service 102 may provide the private computer network130 with the allocated telephony resources for immediate use by theprivate computer network 130. For example, the telephony resourceallocation service 102 may provide the private computer network 130 withtelephone lines and/or telephone numbers for use in conjunction withcall centers maintained by the private computer network 130.

In the event that private network extensions 120 are currently providedfor the private computer network 130, it may be unnecessary to providenew private network extensions 120 for allocating new telephonyresources to the private computer network 130. Instead, it may besufficient to determine whether additional ACD instances should beexecuted on the private network extensions 120.

As illustrated in the block diagram of FIG. 2C, the private computernetwork 130 may accept the allocation of telephony resources offered bythe telephony resource allocation service 102. In response to thisacceptance, the telephony resource allocation service 102 may determinewhether ACD instances currently executing on the private networkextensions 120 are sufficient to support the additional telephonyresources requested. For example, as discussed above, the telephonyresource allocation service 102 may compare the maximum number of callswhich may be distributed by currently executing ACD instances to theestimated maximum number of calls which may be received for distributionshould the requested telephony resources be allocated to the privatecomputer network 130.

If the estimated maximum number of calls which may be distributed by theACD instances exceeds the present maximum number of calls which may bereceived for distribution by the ACD instances with the allocation ofnew telephony resources, the telephony resource allocation service 102may determine that additional ACD instances are needed. The telephonyresource allocation service 102 may then submit a request to the CNS 105to execute additional ACD instances. This request may be submitted alongwith the telephony resources to be allocated to the private computernetwork 130. The additional telephony resources to be allocated to theprivate computer network 130 may be further associated with thepreviously private network extensions 120, including the newly executedACD instances. An acknowledgement of the same may also be transmitted tothe telephony resource allocation service 102.

If the estimated maximum number of calls which may be distributed by theACD instances does not exceed the present maximum number of calls whichmay be received for distribution by the ACD instances with theallocation of new telephony resources, the telephony resource allocationservice 102 may determine that additional ACD instances are not needed.The telephony resource allocation service 102 may then submit only thetelephony resources that are to be allocated to the private computernetwork 130 to the CNS 105. The additional telephony resources to beallocated to the private computer network 130 may also be associatedwith the previously private network extensions 120. An acknowledgementof the same may also be transmitted to the telephony resource allocationservice 102.

Following acknowledgement that the allocated telephony resources areassociated with the private network extensions 120, and optionally thatadditional ACD instances are executed, the telephony resource allocationservice 102 may return the allocated telephony resources to the privatecomputer network 130.

FIG. 3 is a flow diagram of an illustrative routine 300 implemented bythe telephony resource allocation service 102 to allocate telephonyresources to the private computer network 130. The routine 300 begins inblock 302 and proceeds to block 304, where the telephony resourceallocation service 102 receives a request for telephony resources. Asdescribed above, the request may include an amount of telephonyresources desired by the private computer network 130, such as telephonelines and/or telephone numbers for a selected duration of time.

In block 306, the telephony resource allocation service 102 maydetermine whether telephony resources sufficient to satisfy the userrequest are available. For example, the telephony resource allocationservice 102 may review the telephony resources requested and comparethis to the available telephony resources. If the available telephonyresources are greater than the requested amount, the routine 300 maymove to block 316, where a determination is made regarding whether theprivate computer network 130 is an existing private computer network130. If the available telephony resources are less than the requestedtelephony resources, the routine may move to block 310, where thetelephony resource allocation service 102 may respond to the privatecomputer network 130 with the available telephony resources.

In block 312, the telephony resource allocation service 102 maydetermine if the private computer network 130 accepts the offeredallocation of telephony resources. If the private computer network 130does not accept the offered allocation of telephony resources, theroutine 300 may end at block 314. If, however, the private computernetwork 130 accepts the offered allocation of telephony resources, theroutine 300 may move to block 316

The telephony resource allocation service 102 may make a determinationin block 316 whether the private computer network 130 is an existingprivate computer network 130. Such a determination may be made, forexample, determining if private network extensions 120 are or are notpresently provided to the private computer network 130. If privatenetwork extensions 120 are not presently provided to the privatecomputer network 130, then the private computer network 130 may bedetermined to be a new private computer network 130. If private networkextensions 120 are presently provided to the private computer network130, then the private computer network 130 may be determined to be anexisting private computer network 130.

In the event that the private computer network 130 is a new privatecomputer network 130, the telephony resource allocation service 102 mayinstruct that one or more private network extensions 120 be created forthe new private computer network 130 in block 320. In certainembodiments, an instruction for the creation of a new private networkextension 120 may include submitting information regarding the allocatedresources to be provided to the private computer network 130 andconfiguration information for communicating with the private computernetwork 130 to the CNS 105. Upon creation of the new private networkextensions 120 the telephony resources allocated to the private computernetwork 130 may be provided to the private computer network 130 in block322.

In the event that the private computer network 130 is determined to bean existing private computer network 130 in block 316, a furtherdetermination may be made in block 324 as to whether a new ACD instancemay be needed to support the telephony resources which are to beallocated to the private computer network 130. As discussed above, thetelephony allocation resource system 102 may compare the maximum numberof calls which may be distributed by currently executing ACD instancesto an estimate of the maximum number of calls which may be received fordistribution by the ACD instances with the allocation of the newtelephony resources should the requested telephony resources beallocated to the private computer network 130.

If the estimated maximum number of calls which may be distributed by thepresently executed ACD instances does not exceed the present maximumnumber of calls which may be received for distribution by ACD instanceswith the allocation of new telephony resources, the telephony resourceallocation service 102 may provide the telephony resources to theprivate computer network 130 in block 322. If, however, the estimatedmaximum number of calls which may be distributed by the ACD instancesexceeds the maximum number of calls which may be received fordistribution by the ACD with the allocation of new telephony resources,the telephony resource allocation service 102 may request that one ormore new ACD instances be executed to handle distribution of theadditional calls. Upon execution of the new ACD instances, the newlyallocated telephony resources may be associated with new and presentlyexecuted ACD instances and the telephony resources allocated to theprivate computer network 130 may be provided to the user in block 322.The routine 300 may then conclude in block 330.
